Brake fluid acts as a hydraulic fluid, transferring power and lubricating brake system components while also preventing corrosion. It must contend with extreme heat and the inevitable moisture contamination that can lead to a brake system failure. AMSOIL synthetic brake fluids surpass Department of Transportation (DOT) requirements and provide auto enthusiasts and racers with a brake fluid that delivers superior high-temperature performance.

Product DescriptionFights Water Contamination: Water contaminates the brake system by seeping through microscopic pores in fl exible brake lines and seals and through the reservoir fi ll cap. Brake fluid itself is hygroscopic (attracts moisture). Once introduced to the system, water reduces boiling points and compromises performance. It corrodes brake parts, lines and seals, leading to eventual failure. AMSOIL synthetic brake fluid's superior wet boiling points counteract these problems. They lubricate and protect intricate brake components despite the inevitable water contamination. A nitrogen blanket is added to each bottle during manufacturing to purge moisture and ensure the maximum level of performance.

**Wet ERBP: the boiling point of brake fluid having absorbed 3.7 percent water. Only 3.7 percent water contamination is often sufficient to reduce a DOT 3 fluid’s boiling point below the DOT minimum.

Brake Fluid Maintenance
Brake fluids fail either because they boil or because they cease to provide adequate lubrication and corrosion protection. Both reasons for failure are the result of contamination, usually by water or petroleum products.

DOT 3 and DOT 4 polyglycol ether-based brake fluids are hygroscopic, which means they absorb water easily and hold it in suspension, similar to antifreeze. In most climates, moisture seeps into the brake system continuously through the various seals and microscopic pores of the flexible brake lines. This seepage can accelerate as a vehicle ages and there’s almost no limit to how much water the fluid can absorb. By the time brake fluid has been in the system for three years, it can easily reach its wet boiling point. Because this happens gradually, most drivers won’t discover the reduced braking ability until it’s too late.

Many owner’s manuals recommend changing brake fluid every 24 months to remove moisture. Approximately half of all cars and light trucks in the U.S. over 10 years old have never had the brake fluid changed. In addition, powersports applications such as motorcycles, ATVs and UTVs require routine brake fluid changes as well.
